Checking for the Existence of a Column in a SQL Server Table

To check if a column exists in a SQL Server table, you can use the INFORMATION_SCHEMA.COLUMNS system view, which provides information about all columns in all tables in a database. Here’s a SQL query that checks if a specific column exists in a specific table: IF EXISTS ( SELECT 1 FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME = 'YourTableName' AND COLUMN_NAME = 'YourColumnName' ) BEGIN PRINT…

Open Source Note Taking

I know all of you have followed me for the horny posts about sexual violence but I have decided to post some recommendations for open source tools each Friday to promote my other insidious agenda of increased privacy, security, and independence from for-profit companies.

A lot of you here probably like to journal and take notes so I decided to start with some dedicated note taking apps. Of course you can also take notes in LibreOffice and Cryptpad, but those are more general office solutions similar to Microsoft Office or Google Docs.

Freeplane

For most of my my personal note-taking right now I like to use Freeplane. It's free and open source (hence the name), runs on pretty much every desktop, and provides a solid note taking environment. Notes are represented as graphs (typically trees) which can contain cells which have arbitrary data. These cells can be manipulated with a built-in scripting language which allows you to use it like a spreadsheet in addition to using to store notes. Nodes can be folded as well, and you can make decision trees, flowcharts, etc. very easily.

The interface may look somewhat intimidating since it's not just a regular note taking app, and many users take a mind-mapping approach, but you can just imagine it as a nested tree with the nodes closer to the root being broader concepts than the leaves.

Joplin

Joplin is a markdown based tool for note taking, though it provides a WYSIWYG style editor, intra-notebook links, the ability to store templates, to-do lists, and a few more advanced features. It has an android and iOS app as well. If you want to sync your notes between devices you can self-host a server, use some sort of file sharing tool (like KDE Connect), or pay for their service.

I no longer use it (having since moved to Freeplane, KDE PIM, and SQL), but it's a good program and it might be good for your problems since everyone has different needs.

KDE PIM (KOrganiser or Merkuro)

If you use KDE already, KDE has a PIM suite which allows you to create tasks, events, and schedule things. You can use these to take journal entries which can show up in any calendar you share CalDAV info with (which means that you can link most calendar services to it). It can also be used to share when you are free if you like to schedule meetings. I personally use it for my own daily journaling and task management.

Just Plain Markdown

You can also store things in just plain old markdown files (org mode in emacs or just regular .md

files). Many people swear by this and there are some compelling benefits (near universal compatibility with any text editor as well as a very simple interface for extending it). For this you don't really need any specialized tools, just a text editor of your choosing, ideally with some highlighting for markdown. Nearly every text editor has it, so there's not much to say there.

SQL Databases

This is a niche solution, but I am going to mention it anyways since it took me years to actually try it out despite knowing SQL since no one else mentioned it. If you know SQL just using straight up SQL with a SQL database management tool is actually really good. I have done it (and do it) since for some tasks like storing recipes the added structure is actually quite useful. (and you can do complex queries on the data as well) Essentially you just break your notes into different types (possibly even thinking about how to normalize your knowledge representation, though there's a lot of bikeshedding that way) and then turn those types into tables.

Postgresql is my preferred option simply because I use it at work (and let's face it, if you use SQL you probably do to). However, if you aren't already experienced with SQL it isn't something I would recommend. Though I would recommend learning SQL to everyone, since databases have a similar set of capabilities as spreadsheets but are even more powerful and useful.

How to Prevent

Preventing injection requires keeping data separate from commands and queries:

The preferred option is to use a safe API, which avoids using the interpreter entirely, provides a parameterized interface, or migrates to Object Relational Mapping Tools (ORMs). Note: Even when parameterized, stored procedures can still introduce SQL injection if PL/SQL or T-SQL concatenates queries and data or executes hostile data with EXECUTE IMMEDIATE or exec().

Use positive server-side input validation. This is not a complete defense as many applications require special characters, such as text areas or APIs for mobile applications.

For any residual dynamic queries, escape special characters using the specific escape syntax for that interpreter. (escaping technique) Note: SQL structures such as table names, column names, and so on cannot be escaped, and thus user-supplied structure names are dangerous. This is a common issue in report-writing software.

Use LIMIT and other SQL controls within queries to prevent mass disclosure of records in case of SQL injection.

Difference between DBMS and RDBMS

Understanding the difference between DBMS and RDBMS is crucial for anyone diving into the world of data management, software development, or database design. A Database Management System (DBMS) is a software that enables users to store, retrieve, and manage data efficiently. It supports data handling in a structured or semi-structured format, commonly used in smaller applications where data relationships aren’t complex.

On the other hand, a Relational Database Management System (RDBMS) is a more advanced form of DBMS that organizes data into tables with predefined relationships. It uses SQL (Structured Query Language) for querying and maintaining relational databases. RDBMS follows ACID properties (Atomicity, Consistency, Isolation, Durability) to ensure data integrity and supports normalization to reduce redundancy.

Key differences include:

DBMS stores data as files, while RDBMS stores data in tabular form.

DBMS is suitable for single-user applications, whereas RDBMS supports multi-user environments.

RDBMS enforces relationships through primary keys and foreign keys, which DBMS does not.

In today’s data-driven landscape, understanding these systems is essential for cloud database management, data security, and enterprise software solutions. Tools like MySQL, PostgreSQL, Oracle, and Microsoft SQL Server are popular RDBMS examples widely used in web development, data analytics, and ERP systems.

SQL injection

we will recall SQLi types once again because examples speak louder than explanations!

In-band SQL Injection

This technique is considered the most common and straightforward type of SQL injection attack. In this technique, the attacker uses the same communication channel for both the injection and the retrieval of data. There are two primary types of in-band SQL injection:

Error-Based SQL Injection: The attacker manipulates the SQL query to produce error messages from the database. These error messages often contain information about the database structure, which can be used to exploit the database further. Example:  SELECT * FROM users WHERE id = 1 AND 1=CONVERT(int, (SELECT @@version)). If the database version is returned in the error message, it reveals information about the database.

Union-Based SQL Injection: The attacker uses the UNION SQL operator to combine the results of two or more SELECT statements into a single result, thereby retrieving data from other tables. Example:  SELECT name, email FROM users WHERE id = 1 UNION ALL SELECT username, password FROM admin.

Inferential (Blind) SQL Injection

Inferential SQL injection does not transfer data directly through the web application, making exploiting it more challenging. Instead, the attacker sends payloads and observes the application’s behaviour and response times to infer information about the database. There are two primary types of inferential SQL injection:

Boolean-Based Blind SQL Injection: The attacker sends an SQL query to the database, forcing the application to return a different result based on a true or false condition. By analysing the application’s response, the attacker can infer whether the payload was true or false. Example:  SELECT * FROM users WHERE id = 1 AND 1=1 (true condition) versus SELECT * FROM users WHERE id = 1 AND 1=2 (false condition).  The attacker can infer the result if the page content or behaviour changes based on the condition.

Time-Based Blind SQL Injection: The attacker sends an SQL query to the database, which delays the response for a specified time if the condition is true. By measuring the response time, the attacker can infer whether the condition is true or false. Example:  SELECT * FROM users WHERE id = 1; IF (1=1) WAITFOR DELAY '00:00:05'--. If the response is delayed by 5 seconds, the attacker can infer that the condition was true.

Out-of-band SQL Injection

Out-of-band SQL injection is used when the attacker cannot use the same channel to launch the attack and gather results or when the server responses are unstable. This technique relies on the database server making an out-of-band request (e.g., HTTP or DNS) to send the query result to the attacker. HTTP is normally used in out-of-band SQL injection to send the query result to the attacker's server. We will discuss it in detail in this room.

Each type of SQL injection technique has its advantages and challenges.

Yes, moving from SAP ECC to SAP HANA can have several impacts on the existing ECC system. Here are the key areas affected:

1. Database Impact

SAP HANA is an in-memory database, whereas ECC traditionally runs on databases like Oracle, SQL Server, or IBM DB2.

You need to migrate from traditional databases to HANA if you move ECC to SAP Business Suite on HANA.

2. Performance Improvements

Faster processing due to in-memory computing.

Real-time analytics and reporting are significantly improved.

Transactions like MRP (Material Requirements Planning) run much faster in HANA.

3. Simplification of Data Structures

SAP HANA eliminates aggregate and index tables (e.g., no need for tables like BSEG, BSIS, BSAS in Finance).

The Universal Journal (ACDOCA) in S/4HANA replaces many traditional FI/CO tables.

4. Custom Code Adjustments (ABAP Impact)

Certain legacy ABAP programs may not work efficiently due to new HANA-optimized processing.

Need to adapt SQL queries for HANA, avoiding "SELECT *", using CDS Views, and enabling code pushdown.

SAP provides S/4HANA Readiness Checks to analyze custom code compatibility.

5. UI and User Experience Changes

ECC traditionally uses SAP GUI, but SAP Fiori is the default UI for S/4HANA.

Transactions are replaced by Fiori apps, enhancing usability.

6. Functional Module Changes

Some modules and transactions in ECC are simplified or removed in S/4HANA (e.g., SD Rebates replaced by Settlement Management).

SAP Business Partner (BP) replaces traditional customer/vendor master records.

7. Integration with Other Systems

SAP HANA integrates better with SAP BTP, IoT, AI, and ML technologies.

Legacy third-party systems may require interface adjustments for optimized performance.

8. Licensing & Cost Considerations

Self-hosted Integration Runtime (for on-premises and hybrid data movement)

SSIS Integration Runtime (for lifting and shifting SSIS packages to Azure)

Choosing the right IR is critical for performance, security, and connectivity.

1.3 Data Transfer Mechanisms

ADF primarily uses Copy Activity for data movement, leveraging different connectors and optimizations:

Binary Copy (for direct file transfers)

Delimited Text & JSON (for structured data)

Table-based Movement (for databases like SQL Server, Snowflake, etc.)

2. Data Flow Types in ADF

2.1 ETL vs. ELT Approach

ETL (Extract, Transform, Load): Data is extracted, transformed in a staging area, then loaded into the target system.

ELT (Extract, Load, Transform): Data is extracted, loaded into the target system first, then transformed in-place.

ADF supports both ETL and ELT, but ELT is more scalable for large datasets when combined with services like Azure Synapse Analytics.

2.2 Batch vs. Real-Time Data Movement

Batch Processing: Scheduled or triggered executions of data movement (e.g., nightly ETL jobs).

Real-Time Streaming: Continuous data movement (e.g., IoT, event-driven architectures).

ADF primarily supports batch processing, but for real-time processing, it integrates with Azure Stream Analytics or Event Hub.

3. Best Practices for Data Movement in ADF

3.1 Performance Optimization

✅ Optimize Data Partitioning — Use parallelism and partitioning in Copy Activity to speed up large transfers.  ✅ Choose the Right Integration Runtime — Use self-hosted IR for on-prem data and Azure IR for cloud-native sources.  ✅ Enable Compression — Compress data during transfer to reduce latency and costs.  ✅ Use Staging for Large Data — Store intermediate results in Azure Blob or ADLS Gen2 for faster processing.

3.2 Security Best Practices

🔒 Use Managed Identities & Service Principals — Avoid using credentials in linked services.  🔒 Encrypt Data in Transit & at Rest — Use TLS for transfers and Azure Key Vault for secrets.  🔒 Restrict Network Access — Use Private Endpoints and VNet Integration to prevent data exposure.

3.3 Cost Optimization

💰 Monitor & Optimize Data Transfers — Use Azure Monitor to track pipeline costs and adjust accordingly.  💰 Leverage Data Flow Debugging — Reduce unnecessary runs by debugging pipelines before full execution.  💰 Use Incremental Data Loads — Avoid full data reloads by moving only changed records.

4. Common Pitfalls & How to Avoid Them

❌ Overusing Copy Activity without Parallelism — Always enable parallel copy for large datasets.  ❌ Ignoring Data Skew in Partitioning — Ensure even data distribution when using partitioned copy.  ❌ Not Handling Failures with Retry Logic — Use error handling mechanisms in ADF for automatic retries.  ❌ Lack of Logging & Monitoring — Enable Activity Runs, Alerts, and Diagnostics Logs to track performance.

Conclusion

Data movement in Azure Data Factory is a key component of modern data engineering, enabling seamless integration between cloud, on-premises, and hybrid environments. By understanding the core concepts, data flow types, and best practices, you can design efficient, secure, and cost-effective pipelines.

Top 7 Skills you’ll Master in a Full Stack Developer Course

The tech world is evolving rapidly—and so are the roles within it. One role that continues to grow in demand is that of a full-stack developer. These professionals are the backbone of modern web and software development. But what exactly does it take to become one? Enrolling in a full-stack developer course can be a game-changer, especially if you're someone who enjoys both the creative and logical sides of building digital solutions.

In this article, we'll explore the top 7 skills you’ll master in a full-stack developer course—skills that not only make you job-ready but also turn you into a valuable tech asset.

1. Front-End Development

Let’s face it: first impressions matter. The front-end is what users see and interact with. You’ll dive deep into the languages and frameworks that make websites beautiful and functional.

You’ll learn:

HTML5 and CSS3 for content and layout structuring.

JavaScript and DOM manipulation for interactivity.

Frameworks like React.js, Angular, or Vue.js for scalable user interfaces.

Responsive design using Bootstrap or Tailwind CSS.

You’ll go from building static web pages to creating dynamic, responsive user experiences that work across all devices.

2. Back-End Development

Once the front-end looks good, the back-end makes it work. You’ll learn to build and manage server-side applications that drive the logic, data, and security behind the interface.

Key skills include:

Server-side languages like Node.js, Python (Django/Flask), or Java (Spring Boot).

Building RESTful APIs and handling HTTP requests.

Managing user authentication, data validation, and error handling.

This is where you start to appreciate how things work behind the scenes—from processing a login request to fetching product data from a database.

3. Database Management

Data is the lifeblood of any application. A full-stack developer must know how to store, retrieve, and manipulate data effectively.

Courses will teach you:

Working with SQL databases like MySQL or PostgreSQL.

Understanding NoSQL options like MongoDB.

Designing and optimising data models.

Writing CRUD operations and joining tables.

By mastering databases, you’ll be able to support both small applications and large-scale enterprise systems.

4. Version Control with Git and GitHub

If you’ve ever made a change and broken your code (we’ve all been there!), version control will be your best friend. It helps you track and manage code changes efficiently.

You’ll learn:

Using Git commands to track, commit, and revert changes.

Collaborating on projects using GitHub.

Branching and merging strategies for team-based development.

These skills are not just useful—they’re essential in any collaborative coding environment.
